The invention relates to a. sprinkler, and more particularly to the class of street sprinkling machines for street cleaning.

The primary object oi the invention is the provision of a sprinkling machine of this character wherein the swinging nozzle pipes can be readily adjusted simultaneously with the rotation of the sprinkler head so as to direct the water for the watering of the streets to lay the 'dust and dirt thereon when sweeping the same.

Another object of the invention is the provision of an apparatus of this character wherein the water sprinkling heads are retatably supported and are under the control of the operator so that the distribution of water thereit'rom can varied on the street surface for the proper wetting or moistening of the street prior to the sweep ing or the same.

A further object of the invention is the provision of a sprinkler of this character wherein the water discharged therefrom is under positive control at all times.

A still further object of the invention is the provision of an apparatus of this character which is simple in construction, thoroughly reliable and eilicient in operation, and inexpensive in manufacture.

With these and other objects in view the invention consists in the construction, combination and arrangement oit' parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

In the drawingsr-d igure 1 is a side elevation of a street sprinkler constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view there; through. Fig. 3 is a rear end elevation. Fig. i is a top plan view of the sprinkling ipe sectioned on the line 4-4 of Fig 1. gig. 5 is a vertical transverse sectional view on the line 55 of Fig. 1. Fig. 6 is a sectional view on the line (S-6 of Fig. 1.

Similar reference characters indicate. corresponding parts throughout the several views in the drawings.

Serial No. 777,882.

the street sprinkler comprises a supporting bed 10 mounted upon any suitable running gear '11 having front and rear axles 12 and 13 on which are journaled the 'front and rear supporting wheels i l and 15 respectively, the latter being of increased size with respect to the front wheels 14, yet the.

said front and rear wheels may be of uni form size with respect to each other if desired. Stationarily supported upon the bed 10 is a cylindrical tank 16 which is permanently closed at opposite ends and is formed with a partition 18 to provide in its forward portion a compressed air chamber 17, while the rear portion of the said tank serves as a water chamber 18. The air within the said chamber 17 is let into the chamber 18 above the water level therein through a bypass or lead pipe 19, the ends of which being suitably tapped in the body of the tank .16 at the top thereof. The pipe is formed with a valved air outlet nipple 20, a cut-oil valve 21, and a valved inlet nipple 22, to which latter is adapted to be conncctcd a suitable compression pump for supplying air under pressure in the chamber 1'7 while the outlet nipple 20 permits the discharge of air from the compressed air chamber 17 as the occasion may require. Mounted on the pipe 19 for communication therewith is an ordinary pressure gage 23, whereby thepounds pressure of the compressed air within the chamber 17 can be accurately ascertained on inspecting the gage, which operates in the ordinary wellknown manner. The valve 21 is designed to cut oil the supply of air to the chamber 18 above the water level therein or to regulate the inflow of air from the chamber 17 to the said chamber 18 as will be clearly ap arent.

ounted at the point of communication of the bypass pipe 19 with the tanlclG is a float valve cage 24 in which is arranged a spherical float valve which is adapted to engage a seat 526 formed in the end of the bypass pipe 19, and this valve is adapted to be seated on the rise of water within the chamber 18 so as to check the flow of the water through the bypass pipe 19 into the compressed air chamber 17.

Arranged within the tank and suitably tapped within the bottom thereof near the rear end so as to vertically rise from the said bottom is a float valve cage 27 having a crown plate 28 through which is slidably valve 30 upon. the crown 28 when the said i. bl.)

float valve is lifted by the Water admitted into the chamber 18 for the filling thereof. vl hen the chamber 18' is emptied. the lloat valve becomes seated, thereby preventing the escape of compressed air from the chamber 18, the cage 9;? being designed to limit the displacement of the iioat valve and also to guide it to its seat therein,

Arranged beneath the bed 10 and extending from a medial point with respect to the tanlr reared sly thereoi is water do livery pipe fich'includes the pipe 33 and the vertical e 35. The pipes 33 andfi ough the rned "posed in the coupling the pipe lower o Ebb 11 check valve can tor the filling is supported are connectec cross sills v0 or e vertical pipe 35 also serves to s pport e said pipe 33 in horizontal plane as azh bed 10 of the sprinkling ap aratus,

Conne ted to the end. oi the pip 33 is a i -shaped coupling 39 in which tapped lateral, v extending branch pipes to which project outwardly from opposite sides of the said pipe 33. Connected to the outer ends 01 the respective branch pipes 40 are vertically swinging nozzle pipes. Each of the nozzle pipes comprises at its upper end an elbow rotatably connected with its respective branch pipe l0, and at its lower end a section rotatable in a union 39 about a vertical axis lllach rotatable section terminates in an elbow ll which carries at its outer end a sprinkler head 42 arranged in close proximity to the street surface for discharging water thereonto from the chamber 18. branches 40 are provided with gate valves 4L3 actuated through locking levers pivoted to and supported in suitable brackets {l5 mounted upon the said branches ll), the said levers lt being operated in a manner presently described 7 Pivoted ezteriorly to the l6 the forward end theroi' and on opposite sides of the same are throw levers it which ontend upwardly opposite sides of seat l? to be occupi by the tearnster or d oi the street a or driv r ca levers so suitably pivoted to connecting rods 4:8 which are also suitably pivoted to the rock: ing levers it for actuating the gate valves l3 whereby the water can be out of? from the chamber 18 to the sprinkling nozzle pipes having the terminal. elbow it or the flow of water to the latter can be regulated at the will of the said teamster or driver or the street sprinkler Connected to the rotatable sections carrying the elbows are verticalarins 49 which extend upwardly beyond the plane of pipe 35 and each has connected thereto a knuckle joint 50 which unites a turning rod 51 Wlitlf'tllG arm at), The rod is provided with a screw portion 52 working in a hanger 53 and carries hand wheel so that the rod 51 can be turned for adjusting the noz zle ll angularly in a direction. forwardly or rearwardly of the apparatus.
